Choosing the best bypass sliding barn door hardware kit starts with measuring your opening, doors, and ceiling clearance. Single-track kits can save space but usually make the doors overlap; double-track kits let doors move independently but need room for two rails. These four options cover both designs, from a compact 6-foot kit to a longer setup for four doors. Check the listed door limits and included parts against your project before you buy; the doors are not included.

Our Picks: Best Bypass Sliding Barn Door Hardware Kit reviews
1. AONAYIOA 6FT Kit: Higher Stated Capacity in a Compact Track
The AONAYIOA kit uses a single 6-foot track for two wooden doors. Its stated capacity is 330 pounds, and it is listed for doors up to 36 inches wide and 1.18 to 1.57 inches thick. The black powder-coated steel hardware includes rollers, stops, anti-jump discs, spacers, a floor guide, and the other pictured installation pieces. The doors are sold separately.
Its single-track layout keeps the hardware arrangement straightforward, but the doors overlap by about 6.7 inches. That affects how wide each panel needs to be: the product description warns that panels should be wider than the opening so the doors can cover it. Measure the opening and the actual door widths before ordering, rather than assuming two panels will meet in the middle.
This is a useful option when the door thickness and width fit its stated limits and you want a higher stated weight capacity than the other single-track kits here. The main trade-off is the overlap and the relatively specific thickness range. It is not the right pick if your doors are thicker than 1.57 inches or you need the panels to slide without overlapping.
Pros:
- 330-pound stated door weight capacity
- Includes a floor guide, spacers, stops, and anti-jump discs
- Listed for doors up to 36 inches wide
- Powder-coated steel hardware
Cons:
- Doors overlap by about 6.7 inches, so sizing needs care
- Door thickness must be between 1.18 and 1.57 inches
Verdict: Choose the AONAYIOA if your doors fit its size limits and you want the highest stated capacity among these single-track options.
2. SMARTSTANDARD 6.8FT Kit: A Practical Single-Track Choice
This SMARTSTANDARD kit is built for two wooden doors on one 6.8-foot track. It uses carbon steel with a frosted black finish, and its listed door weight limit is 220 pounds. The package includes rail sections and connectors, hangers, wall spacers, a floor guide, stops, hex keys, and other necessary hardware. Doors are not included.
The most important planning detail is its overlap: the product specifies 8 to 12 inches between the doors. Each panel needs to be wider than half of the opening plus the overlap space, or the closed doors may not cover the opening fully. Its 1⅜- to 1¾-inch thickness range is broader than the AONAYIOA’s, though its stated weight limit is lower.
For a typical two-door project, the included instructions and listed installation support may help make setup more manageable. Still, this kit has a tighter weight limit than the AONAYIOA and needs enough panel width to account for the larger overlap. Confirm your door measurements and the exact opening coverage you want before choosing it.
Pros:
- 6.8-foot single-track layout for two doors
- Fits doors 1⅜ to 1¾ inches thick
- Includes spacers, a floor guide, door stops, and connectors
- Installation instructions are included
Cons:
- 220-pound stated weight limit
- 8–12 inches of overlap can affect the door-width calculation
Verdict: The SMARTSTANDARD is a sensible fit for a two-door project when its weight limit, door thickness range, and overlap work with your measurements.
3. HOMACER 12FT Kit: A Flexible Option for Longer, Multi-Door Layouts
The HOMACER kit is a single-track bypass system listed as a 12-foot option for up to four doors. Its design uses bent hangers for bypassing doors on one track, and the product description says the system needs 6 inches of clearance. The steel hardware has a black powder coating, and the nylon roller wheels are intended to reduce noise as the doors move.
The product description states a capacity of up to 220 pounds per complete track and notes that track sizes are available from 4 to 20 feet. For this listing, the supplied title identifies a 12-foot track. That longer length makes it worth considering for a broad opening or a multi-panel setup, but you should confirm the number and width of doors your particular layout needs. The supplied information does not specify a door-thickness range, so check that detail with the seller before purchasing.
Compared with the shorter kits, this one is geared toward a more complex layout. Its single-track construction may help where clearance for a double-track system is limited, but a four-door setup calls for careful planning of panel width, overlap, and travel. Do not assume the track length alone guarantees full coverage of your opening.
Pros:
- 12-foot listing suited to longer openings
- Designed for up to four doors on one track
- Requires 6 inches of clearance, according to the product description
- Stated capacity of up to 220 pounds per complete track
Cons:
- Door thickness limits are not provided in the supplied details
- A multi-door layout takes careful measuring and planning
Verdict: Consider the HOMACER for a longer opening or multi-door design, but confirm door compatibility and plan the overlap before ordering.
4. ZEKOO 8FT Double-Track Kit: Independent Sliding Without Door Overlap
The ZEKOO kit takes a different approach from the single-track options: its two-track arrangement lets the doors slide independently and avoids the overlap associated with a single track. The listing describes an 8-foot double-track setup made from ¼-inch solid carbon steel with a black powder coating. It is listed for doors 1⅜ to 1¾ inches thick.
The package includes four 4-foot rails, rollers, brackets, door stops, anti-jump pads, floor guides, spacers, and lag bolts. Doors are not included. The product description says the system is intended to save space compared with traditional double-door hardware, but it still uses two tracks, so check the available wall and ceiling area and follow the installation instructions closely.
A key limitation is that the supplied details do not state a door weight capacity. That makes it harder to compare directly with the other kits, which do provide weight limits. The listing is also marked unavailable in the supplied product data, so availability may need to be checked before you settle on it.
Pros:
- Two tracks allow doors to slide independently
- No single-track overlap between the doors
- Listed for doors 1⅜ to 1¾ inches thick
- Includes floor guides, spacers, stops, and anti-jump pads
Cons:
- Door weight capacity is not stated in the supplied details
- Listed as unavailable in the supplied product data
Verdict: The ZEKOO is the better design match when independent door movement and no overlap matter, provided it is available and your doors meet the installation requirements.
How to Choose a Bypass Sliding Barn Door Hardware Kit
Choose Between Single and Double Tracks
A single-track kit places both doors on one rail, which can reduce the space needed for the hardware. The trade-off is overlap: the AONAYIOA lists about 6.7 inches, while the SMARTSTANDARD lists 8 to 12 inches. A double-track design, like the ZEKOO, lets doors travel independently and avoids that overlap, but it uses two tracks. Consider your wall, ceiling clearance, and how you want the doors to move.
Measure the Opening and Door Panels
Measure the opening, each door panel, and the space available beside the opening for the doors to slide. With a single-track kit, the overlap affects how much of the opening the doors cover when closed. The SMARTSTANDARD specifies that each panel should be wider than half of the opening plus the overlap space. The AONAYIOA also warns that the panels should be wider than the opening. Use the requirements for your selected kit rather than applying one rule to all bypass systems.
Check Track Length and Door Travel
Match the track length to the opening and the path each door needs to travel. The options here range from 6 feet to 12 feet, and the HOMACER listing describes a 12-foot setup for up to four doors. Make sure your panels can slide clear of the opening without running into a wall, trim, or other obstruction. A long track does not by itself confirm that a particular door arrangement will provide full coverage.
Confirm Door Thickness and Weight
Check your door’s actual thickness and weight against the hardware limits. The AONAYIOA is listed for 1.18- to 1.57-inch-thick doors and a 330-pound capacity; the SMARTSTANDARD lists a 220-pound limit and 1⅜- to 1¾-inch thickness range. The HOMACER lists up to 220 pounds per complete track but does not provide a thickness range in the supplied details. The ZEKOO details specify door thickness but do not state a weight limit.
Review Clearance and Installation Needs
Look at the space above the door and the room available for the track, hangers, and door movement. The HOMACER specifies 6 inches of clearance, while the other listings give their own hardware and installation details. Check the included parts and instructions, and confirm that your wall can support the installation. If you are unsure about mounting or door weight, get qualified help before installing the kit.
Check What Comes in the Box
Compare the included rails, connectors, hangers, spacers, floor guides, stops, and anti-jump parts with your project needs. Package contents differ across these kits, and doors are not included. The ZEKOO listing includes lag bolts, while the other product descriptions list different combinations of hardware. Read the current listing carefully to confirm what is supplied and whether any installation materials are needed separately.
Frequently Asked Questions
What is a bypass sliding barn door hardware kit?
It is hardware that allows two or more doors to slide past one another. Some kits place both doors on one track and use overlap; others use two tracks so the doors can move independently.
Do bypass barn door kits include the doors?
No. The product descriptions for these kits state that the doors are not included. You need to choose door panels that fit the kit’s thickness, weight, and width requirements.
Does a single-track bypass kit always have door overlap?
These single-track products specify overlap. The AONAYIOA lists about 6.7 inches, and the SMARTSTANDARD lists 8 to 12 inches. The amount can affect how wide the panels need to be to cover the opening.
Which kit is best if I do not want the doors to overlap?
The ZEKOO is the double-track option in this selection, and its listing says the doors slide independently with no overlap. Confirm that the two-track layout fits your space and check the listing for availability and weight requirements.
How do I know what track length I need?
Measure the opening, door widths, and the full travel path for each panel. Then compare those measurements with the track length and overlap requirements of the kit. Follow the manufacturer’s installation guidance for your chosen layout.
Can I use any door thickness with these kits?
No. The AONAYIOA and SMARTSTANDARD specify door-thickness ranges, and the ZEKOO lists a range of 1⅜ to 1¾ inches. The supplied HOMACER details do not state a thickness range, so confirm compatibility before buying.
Which kit has the highest stated weight capacity?
The AONAYIOA has the highest stated capacity in the supplied product details at 330 pounds. Make sure your doors meet its width and thickness limits, and check the current product instructions for how the listed capacity applies to your setup.
Final Recommendation
For a compact single-track setup with a higher stated weight capacity, the AONAYIOA is the strongest fit if your doors meet its width and thickness limits. Choose the SMARTSTANDARD if its 8–12-inch overlap and 220-pound limit suit your two-door project. The HOMACER is worth considering for a longer or multi-door layout, while the ZEKOO is the clearest choice for independent movement without overlap—subject to availability and confirming its weight requirements. Measure carefully before ordering, since track style, overlap, door weight, and panel dimensions all affect whether a kit will work for your opening.
